1.) Support- Provides a framework for the body by supporting soft tissues and providing points of attachment for skeletal muscles.
2.) Protection- Internal organs are protected from injury by the skeleton. Ex: Brain is protected by the skull
3.) Movement- Skeletal muscles attach to bones as muscle contracts it produces movement.
4.) Mineral storage and homeostasis- Bones store minerals such as calcium and phosphorus. The bones can then release them as needed to maintain homeostasis.
5.) Site of Blood Cell Production: Red Bone Marrow- is a connective tissue in certain bones that make blood cells. Hemopoiesis- process of making blood cells
6.) Storage of Energy: Yellow Bone Marrow- primarily adipose (fatty) tissue and serves as energy storage for the body

6 Types of Bones
1.) Long Bones
- longer than they are wide.
- Made of two parts (shaft) (extremities)
- Arms, legs, fingers and toes
2.) Short Bones
- Length and width about equal
- Ex: wrist and ankle bones
3.) Flat Bones
- thin and flat
- serves as protection and site of muscle attachment
- Ex: cranial bones, sternum, ribs
4.) Irregular Bones
- complex shapes that cannot be classified into any previous categories
- Ex: vertebrae and facial bones
5.) Sutural Bones
- small bones that form between joints of cranial bones, number varies from person to person
6.) Seasamoid Bones
- small bones in tendons in areas of high pressure
- Ex: patella and in the wrist
